Abstract:
Objectives To establish a new method of determining content of acrylamide in water.
Methods Acrylamide in water was derived for 2, 3-dibromopropionamide and analyzed by gas chromatography with capillary column.
Results The linear correlation coefficient of acrylamide in water was 0.9993.The detection limit was 0.01 μg/L. The average recovery of standard addition was 96.6%, and the average RSD was 5.8%.
Conclusions The advantage of the method was quick, sensitive, specific and suitable for the determination of trace acrylamide in water.
